Answer 1

Which pair shows equivalent expressions?

A.2(2/5x + 2)=2 2/5x + 1

B.2(2/5x + 2)=4/5x + 4

C.2(2/5x + 4)=4/5x + 2

D.2(2/5x + 4)=2 2/5x + 8

Solution:

Let us distribute 2 inside the parenthesis.

That is, we use distributive property:

a(b+c)=ab+ac

So,

Answer:Option (b)

Applying distributive property, a(b+c)=ab+ac

So, Option (B) is correct.
